Morales a late scratch as he awaits birth of child

DENVER -- Left-hander Franklin Morales was a late scratch from Fridays' scheduled start against the Reds as he is now expecting the birth of his child. In his place, the Rockies started right-hander Matt Belisle against right-hander Johnny Cueto.

"Franky's wife is in labor so we're going to improvise," manager Walt Weiss said. "Fortunately, [Jorge De La Rosa] going as long as he did last night gave the bullpen a break. We're in decent position to get through this game."

Weiss learned of the news as he was driving to the stadium around 1 p.m. MT and the situation didn't allow the Rockies an opportunity to bring up an emergency arm from Triple-A Colorado Springs.

"It just happened too late," Weiss said. "The Triple-A club was on the way to Sacramento and there just wasn't enough time to get somebody in here."

Weiss is hoping that Belisle can get through three innings and his cap will be "in the neighborhood" of 45 pitches. Belisle's starting experience with the very same Reds team he'll be facing off against played into Weiss' decision.

"That was the thought that went into it," said Weiss of Belisle, who will be making his first start since May 25, 2008. "Matty has been a starter, the first half of his career really. The other guy out there obviously is [right-hander Juan] Nicasio but he's only had one day off after pitching two innings so we're not really going to get a whole lot of length out of Juan."

Belisle's last outing came Monday, when he tossed two outs against the Padres. In 49 1/3 innings this season, Belisle owns a 4.93 ERA with 58 hits allowed compared with 33 strikeouts. Belisle has seemed to turn a corner as of late, though, with a 1.93 ERA over his last 11 appearances dating back to July 22.

Weiss has a rough idea of the pitchers he'll use to patch nine innings together tonight but nothing is "etched in stone."

"I have in mind the four guys who I'd like to get through about six or seven innings with but not exactly sure the order yet," Weiss said.

As for the plan for Morales moving ahead, the Rockies aren't sure if he'll be available Saturday. If he is, Weiss will use him in relief to protect what's sure to be a ravaged bullpen.

If Morales needs more time away, the Rockies could also put him on paternity leave, which would free up a roster spot while making Morales unavailable for three days.

Tulo, Anderson undergo successful surgeries

DENVER -- The Rockies announced that shortstop Troy Tulowitzki's season-ending surgery on his left hip was successful Friday.

Dr. Marc Philippon performed the arthroscopic operation in Vail, Colo. and found nothing unexpected as he went in to repair Tulowitzki's left labrum.

"It sounds like things went well," manager Walt Weiss said. "He's recovering and the doctor felt like he took care of whatever he had to take care of in there."

Tulowitzki is now looking at five months of recovery but is fully expected to be ready for the start of Spring Training next season.

Tulowitzki was in the midst of an MVP-caliber campaign when he suffered a left hip flexor strain on July 19. Through 91 games, Tulowitzki was batting .340 with a .432 on-base percentage and a .603 slugging percentage.

Entering Friday, Tulowtizki is still tied for the fourth most home runs in the National League at 21. But by the time this season is over, the 2014 Home Run Derby captain will have missed a total of 222 regular-season games dating back to the beginning of the 2012 season.

Most of his injuries have been to his lower body. Tulowitzki is hoping this procedure finally elevates some of the stress in his legs stemming from his torn left quadriceps injury in 2008.

"I'm looking forward to getting back and playing the game I love," Tulowitzki said Wednesday. "I will do everything I can to perform at a high level for the rest of my career. This should answer a lot of the leg issues I have had in my past."

Weiss also confirmed that Brett Anderson's back surgery in Phoenix Thursday was successful as well.

"Anderson is doing well too," Weiss. "His surgery and that injury was pretty straightforward. Everything went well and he should make a full recovery."

Dr. Chris Yeung performed the operation to repair a disk in Anderson's lower back. Like Tulowitzki, Anderson has been slated for a five-month recovery timetable and should be ready for Spring Training.

Anderson only made eight starts for the Rockies after being acquired over the winter from the Athletics.

While he was on the mound, Anderson flashed promise with a 2.91 ERA and 29 strikeouts compared with 13 walks over 43 1/3 innings. But the fact that Anderson hasn't topped 100 innings since 2010 will surely come into play as the Rockies decide whether or not to pick up his $12 million club option for next season.

Rockies to honor Helton all weekend

DENVER -- Friday marks the beginning of the Rockies' three-day celebration of first baseman Todd Helton's career, with it all culminating in his jersey retirement ceremony on Sunday.

The first 15,000 fans in attendance for Friday's game against the Reds received a commemorative Todd Helton "Farewell" bobblehead.

On Saturday, there will be another Helton-themed giveaway with the first 15,000 fans through the gates receiving a Todd Helton Player Collectible Jersey, presented by King Soopers.

And on Sunday, the first 15,000 fans in Coors Field for Helton's retirement ceremony will be treated to Todd Helton "Retire 17" Bobblehead Gnomes.

All weekend long, the Rockies will be using baseballs featuring a No. 17 logo for the three-game series. Likewise, all bases will feature the same logo.

Helton played his entire career for the Rockies from 1997-2013. In those 17 seasons, he earned three Gold Gloves, four Silver Sluggers and five All-Star Game berths.

Helton's finest season came in 2000, when he tied Nomar Garciaparra with a Major League-best average of .372. He also led all of baseball in doubles (59), RBIs (147) and slugging (.698) that year.

Helton is the Rockies' all-time leader in games played (2,519), homers (369), RBIs (1,406), hits (2,519), runs (1,401), singles (1,521), doubles (592) and walks (1,335).
